{"product_id":"yhm-mid-length-gas-tube-blk","title":"Yankee Hill Machine Co Mid-Length Gas Tube – AR-15 Rifles","description":"\u003cp\u003eThis mid-length gas tube is a direct replacement for worn or damaged tubes on AR-15 platform rifles configured with mid-length gas systems. The mid-length system—measuring approximately 9.5 inches from receiver to gas block—offers smoother cycling and reduced felt recoil compared to carbine-length systems, making it a popular choice for 14.5\" to 16\" barrel builds. Replace your gas tube if you experience cycling issues, visible corrosion, or damage from repeated disassembly.\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a black finish to resist corrosion and heat. Installation is straightforward for anyone comfortable with basic AR-15 assembly: remove the handguard, drive out the gas block roll pin, swap the tube, and reassemble. No gunsmithing required, though a roll pin punch set and armorer's wrench are recommended.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Mid-Length Gas Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 rifles with mid-length gas systems (typically 14.5\"–16\" barrels)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in with basic tools (roll pin punch recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube only (roll pin not included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yankee Hill Machine Co","offers":[{"title":"Default Title","offer_id":47941633310975,"sku":"YHM-BL-04M","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2145054.jpg?v=1766569561","url":"https:\/\/doublestackstore.com\/products\/yhm-mid-length-gas-tube-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
